I bought my truck under the assumption that I wouldn't need to do a major tuneup until 100,000 miles. Prior to that, I had to get one at 60,000 miles, 3-5 months after that one of my spark plugs shot out of the motor, leading to having to have the head replace. I received no reasonable explanation on what would have caused that or why would it happened. The dealership and Ford wanted to charge me 3,600 dollars to fix it. I was wondering if anyone else had this problem with a Ford F150 or had there been some kind of recall? if so, is there some kind of legal action I can take against Ford for this.

2002 Ford F150 5.4 liter engine 2 months ago I had a spark plug thread failure on my F150. It cost $400 to repr the vehicle so that it could be driven. 1500 miles later I have another thread failure causing another plug to be spit out of MY6 cylinder head. I have been told by dealerships and mechanics that this is a common problem and that I can replace the heads with new ones but that they can not guarantee that it would not happen again. Or I can have both heads removed and have inserts machined into the heads to prevent anything from failing again. The cost of this process is $2200. I have now spent $2600 on the engine in 2 months time due to a improper manufacturing of the heads that were made for this engine. I would like to see a defect recall made on the heads and possibly be reimbursed for some of the expense.

The ignition shut off unexpectedly. The vehicle was towed to a service dealer and they were unable to resolve the problem. There was no code for the check engine at the early stages of the problem. The engine died and the consumer's vehicle drifted into the other lane. The service dealer found that the cam sensor was bad and the exhaust sensor was replaced.

I made a trip to California and right before I left I had the oils changed on my truck. My truck had about 15,000 miles on it. The trip was 1,000 miles round trip and it used 2 1/2 quarts of oil. I took it to the dealer and was told that it was normal to use that much oil. And they changed the oil to a different weight to do a test on oil consumption. It still uses oil and now the motor smokes when you first start it up. And if it sits for a couple of days it will know loud when you start it. The for D dealer said this is normal.
